(80 quick) a pair of equations is shown below: y = 7x − 8 y = 5x − 2 part a: explain how you will solve the pair of equations by substitution or elimination. show all the steps and write the solution (explain in complete sentences, you can use numbers in explanation) part b: if the two equations are graphed, at what point will the lines representing the two equations intersect? explain your answer (complete sentences)

A. You can solve the system of equations with substitution.

Step-by-step explanation:

y=7x-8

y=5x-2

7x-8=5x-2

move 8 to the other side and it becomes positive, move 5x to the other side and it becomes negative.

7x+5x=8-2

two negatives make a positive so 5x is positive.

12x=6

12/12 =6/12

x=0.5

plug x into one of the equations

7(0.5)-8

3.5-8 = -4.5

x=0.5 y=-4.5

the one that has a slope of 1/2 and is positive.
